Development of treatment system for eating disorders using personal digital assistants

本研究的目的是为开发一种新的饮食失调治疗系统做准备，其结果如下。为了调查多动这一重要的临床症状，我们要求患者和健康对照者佩戴加速度计来评估客观的身体活动。我们发现，神经性厌食症（AN）限制型患者的体力活动昼夜节律期明显比健康对照组提前，而AN患者体力活动消耗的能量比健康对照组少。此外，我们开发了计算机化的生态瞬间评估（EMA）系统，用于评估和记录症状、行为和食物摄入，这将能够应用于自然环境中的干预。

The results of the present study, the aim of which was to prepare for developing a new treatment system for eating disorders, were as follows. To investigate hyperactivity, one of the important clinical symptoms, patients and healthy controls were asked to wear accelerometers to assess objective physical activity. We found that the phase of the diurnal rhythm of physical activity significantly moved more forward in anorexia nervosa (AN) restricting type than in healthy controls while consumption energy by physical activity was smaller in AN patients than in controls. In addition, we developed computerized ecological momentary assessment (EMA) system for assessing and recording symptoms, behavior, and food intake, which will be able to apply to intervention in natural settings.
